摘要
2-Carbonyl propionic acid-4-methyl benzoyl hydrazone （PAMH） has been synthe-sized by using 4-methyl benzoyl hydrazine and pyruvic acid as the chemicals and acetic acid asphase transfer catalyst under microwave radiation. Then the PAMH and TbCl3·6H20 are placed inthe methanol/acetone/water （3：2：4） mixture for coordination reaction, getting the Schiff complexTb（PAMH）3. The crystal structure is characterized by elemental analysis, X-ray Diffraction （XRD）and infrared spectrum. The compound crystallizes in the monoclinic space group P21/n, with a =1.4770（4）, b = 1.2864（3）, c = 1.9287（5） nm, β= 92.06（3）°, V= 3.6623（15） nm3 and Z= 4. Tb（Ⅲ） ionis nona-coordinated by three completely deprotonated PAMH ligands in a tricapped trigonal prismgeometry, leaving a zero-dimensional mononuclear configuration. The optical properties and thermalstability are studied by ultraviolet spectrum, fluorescence spectra and thermogravimetric analysis（TGA）. The antibacterial activities of the ligand and rare-earth complex are preliminarily studied,and found they have certain antibacterial activity on fusarium solani, and the complex is obviouslymore effective in suppressing fusarium solani than the ligand.
